We can use srcu read lock for BLOCKING and rcu read lock for non-BLOCKING,

Hello Ming,
The lock checking algorithms in the sparse and smatch static checkers
are unable to deal with code of the type "if (condition) (un)lock()". So
unless someone has a better proposal my preference is to use the
approach from the patch at the start of this e-mail thread.
Thanks,
Bart.
